Description

TECHNICAL FIELD The present invention relates to a pachinko game machine, and more particularly to a machine provided with a means for detecting whether or not a pachinko ball has entered or released.

"Prior art" In a pachinko game machine, it is necessary to accurately grasp the so-called ball-in from the player and the ball-out as a prize for the ball in the safe hole. It is the most important information for customer management.

Therefore, as a conventional technique for detecting the passage of a pachinko ball on the passage of the pachinko game machine, there is one disclosed in Japanese Patent Publication No. Sho 64-3506.

That is, the publication discloses that an upper sheet and a lower sheet having a contact point pair are provided, and when the pachinko ball is placed on the upper sheet, the pachinko ball is detected by conducting the contact pair by the weight of the pachinko ball. Has been done.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technique, since the pachinko balls can be detected only in the flow path of the pachinko game machine, the pachinko game machine has a safe hole and a pachinko machine on the out hole. There was a problem that it was not possible to detect how the balls entered, and it was not possible to know the progress of the game, and there was a lack of functions for accurate management of the pachinko game machine.

The present invention has been made in view of such a conventional problem, and detects a safe ball and an out ball on a board of a pachinko game machine, and a pachinko ball detecting means that does not require complicated installation or adjustment.

"Operation" When a constant signal is transmitted to each of the transmission coil row groups of the detection matrix, the reception unit of the reception coil row and the transmission unit of the transmission coil row are inductively coupled to each other, and a predetermined impedance value is generated in the transmission coil row.

When a pachinko ball is applied to the detection unit in which the transmission unit and the reception unit are superimposed, the impedance value changes, and the position is detected by detecting the transmission coil row in which this impedance value has changed and the reception coil row in which the reception current has changed. Can be grasped as coordinates.

The detection matrix is attached along the plane where the pachinko balls are lined up, and the position of the pachinko balls can be known from the coordinates.

When the detection matrix is attached along the board surface of the pachinko game machine, the progress of the game is monitored by making the detection unit correspond to the important points such as the safe hole and the out hole of the board surface, and the situation of the incoming and outgoing balls. Knowing the information, you can use it as data for stopping control, checking for abnormalities due to fraud, and adjusting nails.

While the receiving coil row group is arranged on the front side, the transmitting coil row group is arranged below the receiving coil row group, and the transparent conductive film for shielding is arranged on the front side of the receiving coil row group, it is a transparent conductive film. The electrical effects of the proximity of metals and derivatives from the surface are shielded, eliminating detection errors and protecting against fraudulent activity.

When the transmission coil row group is arranged on the front side and the reception coil row group is arranged under the transmission coil row group, the transmission coil row group serves as a shield to protect the receiving side which is easily affected.

The transmission unit and the reception unit have a rectangular shape, and if the patterns are arranged so as to be orthogonal to each other, the detection unit operates accurately.

[Examples] Various examples of the present invention will be described below with reference to the drawings.

1 to 5 show a first embodiment of the present invention.

As shown in FIG. 1 and FIG. 2, a pachinko game machine 1

The pattern shape of the transmission unit 22a and the reception unit 26a may be delicate in consideration of the size of the pachinko ball B. If it is too large, the resolution is poor, and if it is too small, multiple detections for one pachinko ball B are made. The units react and it becomes difficult to grasp the positional relationship. The thickness of the conductor also has a large effect, and if it is thin, the impedance is too high, and if it is thick, the inner diameter of the pattern becomes small, resulting in poor sensitivity.

When the pachinko ball B passes through the detection unit 20a where and are superimposed, the impedance value of the transmission coil row group 21 changes and the reception current of the corresponding reception coil row 26 also changes.

The position of the pachinko ball B can be grasped as the coordinates of the position where the matrix intersects by detecting the transmitting coil row 22 in which the impedance value has changed and the receiving coil row 26 in which the receiving current has changed.

The detection matrix 20 is connected to a management device (not shown),
This management device stores the positions of the detection units 20a, 20a ... Corresponding to the safe holes 14a, 14a ... And also the positions of the out holes 15. The management device monitors the incoming state of the pachinko ball B as the game progresses.
Depending on the situation, it is used as data for stopping management, checking for abnormalities due to fraud, and for nail adjustment.

The transparent conductive film 28 shields and protects the detection matrix 20 from being electrically affected even if a metal or a derivative such as a human body or a foreign substance approaches the surface glass body 16.
